Though he had always hated slavery, President Lincoln did not believe the Constitution gave him the authority to bring it to an end-until it became necessary to free the slaves in order to save the Union.
D seems like the right answer, but I'm not 100% sure
SNCC became more militant and pushed aside many members.
- Violence against SNCC members increased as the organization became more politically active. In response, as a supporter of the burgeoning "Black power" movement, a subset of late 20th-century Black nationalism, SNCC transitioned from a philosophy of nonviolence to one of greater militancy after the mid-1960s.
- Many SNCC members experienced violence and arrests once more. During the 1964 Freedom Summer, the SNCC concentrated its efforts in Mississippi. In Mississippi, SNCC members concentrated primarily on voter registration campaigns, and their work helped the Voting Rights Act of 1965 gain traction.
- As it moved closer to militancy, SNCC started to concentrate on urging African Americans not to enlist in the American Army. When Stokely Carmichael, who had directed the voter registration drive in Lowndes County, was chosen as the group's new leader in May 1966, the radicalism of the group reached a peak.
Thus this is how SNCC changed in the late 1960s.
